Abstract
The invention relates to a high-strength moisture-proof paperboard surface treatment agent, which can effectively solve the problems that the conventional paperboard adhesive does not have a good using effect and the prior art has potential safety hazard and pollutes the environment. According to the technical scheme, the paperboard surface treatment agent is prepared from the following components in parts by weight: 100 parts of water, 25 to 35 parts of corn starch, 2 to 4 parts of alkali liquor, 1 to 3 parts of reinforcing agent, 0.45 to 0.55 part of tackifier and 0.45 part of surface sizing agent. The paperboard surface treatment agent is prepared by the following steps of: adding the water, the corn starch, the alkali liquor, the reinforcing agent and the tackifier into a glue making machine, stirring for 45 to 55 minutes to form paste, adding the surface sizing agent when the new paste is ended, stirring for 3 to 5 minutes, and thus obtaining the paperboard surface treatment agent. Through the paperboard surface treatment agent, waterproof and moisture-proof properties of a paperboard can be greatly improved, and the bonding strength of the paperboard is improved.
Description
Technical field
The present invention relates to a kind of HS damp-proof paperboard surface treatment agent.
Background technology
The tackiness agent of corrugated cardboard is exactly the adhesives that fluting board and facial tissue or sandwich paper's strong bond is constituted together corrugated cardboard; The quality of its adhesiveproperties; To pop strength, the side pressure strength of corrugated cardboard and carton, expose intensity and ultimate compression strength etc. direct influence arranged, be a key factor that is related to corrugated cardboard and carton; Except this adhesiveproperties when the initial use of tackiness agent, it is along with under the more situation of the variation of weather environment, particularly moisture; When corrugated cardboard is stored; Under the situation of damp formula suction, the adhesiveproperties of tackiness agent reduces greatly, has had a strong impact on the use of corrugated cardboard.
In order to solve above-mentioned shortcoming; Existing technology adopts Surface Size TMB (TMB), formaldehyde, urethane usually, gather moistureproof reinforcing aidss such as ethanol waits the moistureproofness that strengthens corrugated cardboard; But TMB has carinogenicity, formaldehyde, urethane, gathers moistureproof reinforcing aidss such as ethanol and causes environmental pollution easily.
Summary of the invention
To above-mentioned situation; For overcoming the defective of prior art; The present invention's purpose just provides a kind of HS damp-proof paperboard surface treatment agent, can effectively solve the bad problem that has potential safety hazard and environment is polluted with prior art of existing cardboard tackiness agent result of use.
The technical scheme of its solution is that surface treatment agent involved in the present invention is processed by the component of following weight meter: 100 parts in water, W-Gum (80-100 order) 25-35 part, alkali lye 2-4 part; Toughener 1-3 part, tackifier 0.45-0.55 part, 0.45 part of Surface Size at first adds water, W-Gum, alkali lye, toughener, tackifier in the glue making machine; Stirred 45-55 minute, and processed pasty state, when the paste of new system finishes; Add Surface Size, stirred 3-5 minute, accomplish and make;
Said water mainly plays dilution, infiltration, all even diffusions;
Said alkali lye is that mass concentration is 10% sodium hydroxide solution;
Said Surface Size is that AKD alkyl ketene dimer and emulsifying wax stir under the situation of 80 °-85 ℃ of reactor temperatures by weight 6:1 and formed in 25-30 minute; Emulsifying wax is widely used, and price is low, compares with similar tackiness agent auxiliary agent; Be 1/3 of other prices, wide material sources;
Said toughener is the dead front type waterborne curing agent;
Said tackifier are borax; That borax has is crosslinked, the effect of complexing and thickening; The borax consumption is too much, can make between the starch molecule in the tamanori cohesive force strong excessively, and glue becomes rubber-like; Lose bond strength and make blowing or come unstuck, consumption is few or need not just not have the effect of complexing and thickening.
The present invention can improve the waterproof and dampproof property of cardboard greatly, improves the bonding strength of cardboard.
Embodiment
Below in conjunction with embodiment particular case of the present invention is done further explain.
Embodiment 1:
The present invention is processed by the component of following weight meter: 100 parts in water, 25 parts of W-Gums, 2 parts of alkali lye, 1 part of toughener; 0.45 part of tackifier, 0.45 part of Surface Size adds water, W-Gum, alkali lye, toughener, tackifier in the glue making machine; Stirred 45-55 minute, and processed pasty state, when the paste of new system finishes; Add this Surface Size, stirred 3-5 minute, accomplish and make.
Embodiment 2:
The present invention is processed by the component of following weight meter: 100 parts in water, 30 parts of W-Gums, 3 parts of alkali lye, 2 parts of tougheners; 0.5 part of tackifier, 0.45 part of Surface Size adds water, W-Gum, alkali lye, toughener, tackifier in the glue making machine; Stirred 45-55 minute, and processed pasty state, when the paste of new system finishes; Add this Surface Size, stirred 3-5 minute, accomplish and make.
Embodiment 3:
The present invention is processed by the component of following weight meter: 100 parts in water, 35 parts of W-Gums, 4 parts of alkali lye, 3 parts of tougheners; 0.55 part of tackifier, 0.45 part of Surface Size adds water, W-Gum, alkali lye, toughener, tackifier in the glue making machine; Stirred 45-55 minute, and processed pasty state, when the paste of new system finishes; Add this Surface Size, stirred 3-5 minute, accomplish and make.
The present invention is through improving surperficial treatment agent formula; Using alkyl ketene dimer is main raw material; Become perviousness surface treatment agent AKD (emulsion) through reaction kettle production, the product after the improvement adds adhesive for corrugated paperboard again and mixes, and does not influence the bond properties (perviousness: be meant that this surface treatment agent itself just has penetrating quality preferably in the tackiness agent use of tackiness agent; Fusing point is low and do not change the sticking and performance of tackiness agent); Under the situation that has guaranteed the corrugated cardboard intensity effect,, form a protection waterproof membrane with tree lace at stupefied point of fluting board and facial tissue (or core paper) because this surface treatment agent can also solidify rapidly; Thereby improve the waterproof and the humidity resistance of corrugated cardboard greatly; The efficient of getting damp is low, (at first beginning from corrugated cardboard tree lace junction because the corrugated cardboard suction is got damp), pollution-free, environmental protection.
Corrugated cardboard is in moulding corrugation process, and facial tissue is when crossing preheating wheel, and the surface temperature of corrugation roller and preheating wheel is more than 160 ℃; So top sizing layer of boxboard and Corrugating Base Paper or destruction is to a certain degree arranged in moulding and recombination process; Particularly the stupefied point (bonding place) after the moulding of Corrugating Base Paper corrugation destroys greatlyyer in pressure roll effect lower surface glue application layer, and easy moisture absorption causes cardboard or the carton intensity of getting damp to reduce, and the present invention can be effectively at the bonding effect that does not influence tackiness agent between corrugation and the facial tissue about 60 ℃; And can cover the sticking of corrugation and facial tissue effectively and locate; That is to say, sticking and locate and can effectively protect tree lace, nonhygroscopic; Thereby avoided cardboard or the carton intensity in production or use unaffected, played the enhanced effect.
The present invention has following data through verification experimental verification:
The present invention fills a prescription rationally, and manufacture craft is simple, and impermeable ability and bond strength all improve greatly, when solving problem of environmental pollution, can fundamentally solve cardboard or carton produce or use in make moist easily and cause influencing the problem of cementability.
